It's nice to see the Quantum Corporation (NASDAQ:QMCO) share price up 15% in a week. But will that heal all the wounds inflicted over 5 years of declines? Unlikely. Indeed, the share price is down a whopping 86% in that time. The recent bounce might mean the long decline is over, but we are not confident. The real question is whether the business can leave its past behind and improve itself over the years ahead. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

The recent uptick of 15% could be a positive sign of things to come, so let's take a look at historical fundamentals.

We've found 21 US stocks that are forecast to pay a dividend yield of over 6% next year. See the full list for free.

Quantum wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Shareholders of unprofitable companies usually desire strong revenue growth. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last five years Quantum saw its revenue shrink by 3.7% per year. That's not what investors generally want to see. The share price fall of 13% (per year, over five years) is a stern reminder that money-losing companies are expected to grow revenue. We're generally averse to companies with declining revenues, but we're not alone in that. Fear of becoming a 'bagholder' may be keeping people away from this stock.

A Different Perspective

It's nice to see that Quantum shareholders have received a total shareholder return of 41% over the last year. Notably the five-year annualised TSR loss of 13% per year compares very unfavourably with the recent share price performance. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. To that end, you should learn about the 5 warning signs we've spotted with Quantum (including 2 which make us uncomfortable) .
